Hi All, I am wondering if someone here knows where to buy a 1/2” drive crankshaft turning socket for a G35. I can find all kinds of sockets available for American-made cars, but I am striking out trying to find a socket made for the G35. Even if I could find the crankshaft nose diameter and knew the key width, that would be a tremendous help. I am preparing to replace my water pump and haven’t torn into the engine yet. If I can’t find an answer before I get to that point, then I’ll just have to measure it once I get there and hope I can find a socket that doesn’t take a week to arrive. Any help would be much appreciated!

 

iirc it was 19mm ??

I'll try to remember to check tomorrow while I've got the car up in the air doing a tranny fluid change. Hopefully someone else chimes in before that

 

Thanks cleric670 for your help! While you’ve got this one up in the air, would you mind measuring the key width as well? It should be something like 3/16” or 1/4” (not sure if they go by mm or inches for the key). Thank you much!

 

I am hopeful that one of these American-made sockets might be a good fit. If I have an O.D. for the crankshaft snout, and a key width, I should be able to either match it up to one of these, or at least contact ProForm Parts and see if they can find a match.

Ohh if you just need the woodruff key it's Nissan part number 00926-51600, if you need two just go to your local Nissan and buy them it's usually an in stock item since it's literally the same key for every single Nissan/Infiniti with a 6 or 8 cylinder engine from like 1990 to present. It's less than $5 for both.

You could probably call your local Nissan and have them measure one off the shelf if you just need measurements.

I wasn't planning on actually pulling the crank pulley today, thought you needed the pulley socket size I'm not sure I could get an accurate measurement with out at least pulling the fans to get my head in there with a pair of calipers or a measuring tape.

There are two woodruff keys, one for the crank, one for the timing chain sprocket.

 

Sorry I didn't click the link, now I see what you're doing, you wanted an actual turning socket so you can spin the crank with the pulley removed.

Honestly I didn't even know these things existed! I've always just sprayed a little WD40 on the crank to make it easy to put the pulley back on/off (slides on easily with your hand, don't need to press/pull it on/off), pulled the spark plugs so there is no compression and then just rotated the crank pulley with my hands.

Pretty cool they make an actual socket for it though.

 

Thanks again, cleric670. Yes, I am looking for the crankshaft turning socket, but may also try your method of turning by hand as I will be replacing all 6 spark plugs in the process. Thank you for taking time to help!
